Undeclared QMutableListIterator

[aselafernando]

When Compiling the following error is experienced with the master branch on Debian 11 x64

../../app/panelitemsmodel.cpp: In member function ‘void PanelItemsModel::setPluginList(PluginList*)’:
../../app/panelitemsmodel.cpp:58:23: warning: unused variable ‘plugin’ [-Wunused-variable]

I tried adding #include <QMutableListIterator> into app/panelitemsmodel.h however that made no difference..

Hi @aselafernando

What version of Qt are you using? I haven't yet come across this issue, but will try to replicate it.

[aselafernando]

Output of qmake --version

QMake version 3.1 Using Qt version 5.15.2 in /usr/lib/x86_64-linux-gnu

Can replicate using these steps:

git clone --recursive https://github.com/viktorgino/headunit-desktop.git
cd headunit-desktop
protoc --proto_path=modules/android-auto/headunit/hu/ --cpp_out=modules/android-auto/headunit/hu/generated.x64/ modules/android-auto/headunit/hu/hu.proto
mkdir build && cd build
qmake PREFIX=/opt/hud/ ../headunit-desktop.pro
make -j30

I just compiled direct on the raspberry pi 4 and it does not produce the above error, it's only when compiling for x64

qmake --version
QMake version 3.1
Using Qt version 5.15.2 in /usr/lib/aarch64-linux-gnu

That's rather odd. I never had issues on Raspbian or Manjaro. Will have to give building on Debian a go

[aselafernando]

I re-created my development VM and the issue went away, must've been some issue with the QT5 installation on that Debian VM!
